Consider the geometry shown in the figure. The upper right quadrant is filled with a medium with a refractive index V3 and the rest of space is vacuum. A plane wave is n2 = incident on the xy plane from the left with an incident angle "1 = of 60 degrees. Its electric field is linearly polarized along the y direction. Find the power reflection and transmission coeffi- cients at the ryY plane and at the yz plane, respectively. What if the electric field is polarized in the xz plane? n2 = V3 y O
